   Log Message:
   For some reason lost in obscurity and time, I did not ever implement a
   timeout capability to these drivers.  Apparently no one has ever had
   scsi devices that failed to complete a scsi operation in some fashion,
   or at least no one has reported it as best I can remember.  I've just
   run into this situation and figured out that one disk would fail to
   complete an I/O transaction and never timed out.  Add the appropriate
   timeout function to reset the controller and restart things.


the MI esiop driver seems to have the same problem.  before i had
interrupts working on the sunblade 2000, esiop would hang my system
when it was probing disks.  other cards gave errors or hung for a
while, but alawys returned.
